7 Introduction Required Services The following services must be available prior to installation of the spa equipment. A 30mA protected electrical supply isolated adjacent to the location of the spa pack. A header tank to provide a permanent water supply to top up the balance tank and a mains water supply for filling the spa. A trapped drain must be available adjacent to the filtration unit and balance tank. Check the drain provided is capable of taking the pumped discharge water. Heat exchangers require a 60 C primary hot water supply fed via a sprung return valve. A gas supply is only required if a spa gas heater has been specified. Equipment Location The spa pack should be sited in a ventilated and dry area, as near to the spa as possible. It must also be easily accessible for regular service. Check the relevant services mentioned above have been provided and the area is ready to receive the equipment. The type of filter supplied depends upon the commercial spa pack purchased. All systems operate within a 6 minute turnover period. Page 3

8 Equipment Description Light Commercial Sand Filter (Skimmer and Overflow Spas) A hi-rate fibreglass tank operating at 34.30m³/m²/hr, filled with 16/32 grade sand. There is a multiport valve fitted to control water flow through the filter. Sand filter media will require regular cleansing by backwashing at a rate of 30.00m³/ m²/hr to 40.00m³/m²/hr. Regular chemical cleaning with an approved cleaner such as Guardex Filter Cleaner is recommended. Complete media replacement will vary depending on the amount of spa use. High Calcium levels or ph, combined with excessive filter pressure can cause the filter element to become blocked or scale up. Heavy Commercial Sand Filter (Overflow Spas Only) A deep bed fibreglass tank 34.30m³/m²/hr filled with 16/32 grade sand. Sometimes media beds of mixed grades of sand and pebbles are used. It is essential for the efficiency of the filter that the correct media grade and quantity is used. There is a multiport valve fitted to control water flow through the filter. Sand filter media will require regular cleansing by backwashing at a rate of 30.00m³/ m²/hr to 40.00m³/m²/hr. Regular chemical cleaning with an approved cleaner such as Guardex Filter Cleaner is also recommended. Complete media replacement will vary depending on the amount of spa use. High Calcium levels or ph, combined with excessive filter pressure can cause the filter media to become compact and fissuring will occur. This will require a media change. Page 4

9 Equipment Description Heavy Commercial DE Filter (Overflow Spas Only) This tank contains elements made of cloth covered filter grids mounted in a spiral pattern and includes a multiport valve. The filter operates at 5.00m³/m²/hr and is charged with Diatomaceous Earth (DE) filter media, this allows water to pass through, leaving particles of dirt and debris trapped in the powder. Diatomaceous Earth filters discharge the DE powder to waste when backwashing and require refilling before restarting the filter cycle. To recharge the filter add the required amount of media to the spa balance tank at a rate of 0.49kg per m² of filter area. Regular chemical cleaning of the internal filter grids with an approved cleaner such as Guardex Filter Cleaner is also recommended. The following table shows the area of the filter: Filter Tank Ø Filter Surface Area DE Media Required 24ft² 2.14m² 1.05kg 36ft² 3.25m² 1.59kg 48ft² 4.37m² 2.14kg 60ft² 5.39m² 2.64kg 72ft² 6.50m² 3.19kg Page 5

10 Equipment Description Multiport Valve Controls the water flow of the filter, typical functions include: filter, rinse, backwash, recirculate and waste. Exact functions will depend on the filter and valve used. Control Panel Electronic Swimmer spa panel controlled by a two button touch pad located adjacent to the spa. Filter Pumps and Massage Pumps The filter pump(s) are single speed, self-priming models. The pumps vary in size from 0.5hp to 2.0hp. The strainer baskets should be regularly checked, cleaned and debris removed. The pumps have "sealed for life" bearings and durable water seals; they must never be run dry as this will cause the water seal to fail. This is not covered by the warranty. Electric Heater The heaters range up to 9kW single phase to 12kW three phase. The maximum operational water temperature should be no higher than 40 C. The control panel is also fitted with a manual re-settable hi-limit stat set at 45 C. Heat Exchanger (Optional) The heat exchanger option is 18kW, supplied loose and not plumbed to the pack itself. For heat exchanger packs, a primary hot water supply of 60 C will be required fed via a sprung return valve. The heat exchanger must be mounted and plumbed according to the individual instructions supplied with it. Failure to observe correct orientation and piping layouts can cause the unit to operate incorrectly and void any warranty. Page 6

11 Equipment Description Flow/Pressure Switch A flow/pressure switch is fitted within the electric heater for heat exchanger packs. A flow switch should be plumbed into the filter line to protect the heating system and spa pack. Poor water flow will result in the heater failing to operate. If the heater fails, check there is sufficient water flow. A dirty filter is the most common cause of the heater failing to operate. Air Blower A single or three phase continuously rated commercial blower of 1.3kW or 1.7kW respectively is supplied with all commercial spas. The air filter should be replaced annually. Air blowers must be protected from water tracking back onto the motor by an air loop and non-return valve. A non-return valve on its own is not an acceptable means of protection. Light A 240V output is suppied for the spa light. A suitable transformer must be used. Page 7

12 Plumbing Only competent engineers with previous spa installation experience should install Swimmer spa packs. It is the responsibility of the installer to ensure the work is carried out in accordance with SPATA or to local regulation requirements. Pipework must be designed with the minimum number of bends to ensure maximum flow and return to the spa. Please refer to pump performance and permitted pipe flow rates tables opposite for actual pipe recommendations. We also recommend up-rating the pumps for runs of more than 10m head loss. Where the pipework involves long runs and many elbows, the pipe size may need to be further increased. It is recommended in accordance with good practice that all pump suction and returns are valved to enable ease of pump removal.

The lines must be protected by an air loop (recommended to extend to a minimum of 300mm (12") above the normal water level in the spa). A non-return valve should be fitted adjacent to the air connection on the spa. If the recommended height for the air loop cannot be achieved, a double air loop with a spring check valve should be used. Page 9

14 Plumbing Balance Tank Installation (for Swimmer Overflow Spas only) The balance tank is supplied plumbed with linked suctions, overflow inlets and a topup ball valve. Connection to the mains water supply should be via a double check valve or break tank. Float switches, for low level pump protection are supplied fitted to the tank. A second float switch can be fitted as an additional option for solenoid top-up. Note: The float switches are make and break type and polarity is not critical. The balance tank must be fully supported and should be sited with its base on the same level or below the spa floor, never above. Note: Where the tank is lower than the spa, good quality check valves must be used to prevent backflow from the spa shell into the balance tank when the filter pump is turned off. The overflow from the spa to the balance tank is by gravity. To prevent the spa water backing up and flooding the perimeter spa channel, the pipes leading to the balance tank should be a minimum of 63mm (2") diameter for spas with four outlets and 90mm (3") for spas with only two outlets. These pipes should be laid to a fall in all cases with a minimal amount of bends. The use of swept bends rather than 90 or 45 elbows is strongly recommended. To monitor and control the operational water volume in the spa system, an optional electronic water level device is available upon request. Note: Balance tanks require regular cleaning and must be sited to allow for easy access. Page 10

17 Electrical A suitably qualified electrician (preferably also a member of NICEIC or local regulating authority) must carry out the electrical installation. Failure to comply with safety regulations may void any warranty supplied by Golden Coast. All electrical supplies to the spa system must be protected by a 30mA residual current device (RCD) not supplied. Thermostat Programming To set the temperature control, ensure the heater switch is on and the display is illuminated. An operating temperature of 37 C is recommended, however, be aware that the acrylic shell warranty has a maximum limit of 40 C Press the button marked P until the display flashes. Using the up and down arrow button set the desired temperature. When the desired temperature is reached press P and the current temperature will be displayed. Page 13

18 Electrical Filter Operation Commercial spas should be programmed for continuous filtration. The filter will collect debris on the surface of the media which will need to be removed to ensure satisfactory filter operation. Backwashing cleans the filter and removes any debris by reversing the flow of water inside the filter and washing it away to waste. The reading on the filter pressure gauge when the system is first started up will be the clean reading and should be approximately 7-10 PSI, but can be more or less depending on the pipework runs and equipment used. Use this reading and reference it against the reading after subsequent filter cleanings. Backwashing should be undertaken when the pressure reading increases by 7 PSI. After backwashing the pressure reading should return to the clean reading. Failure to return to this reading could indicate a fault is developing with your system. The filter is a pressure vessel and should not be subjected to elevated pressures. Under no circumstances should it be run at pressures exceeding 20 PSI. Dilution of spa water in commercial spas should be at a rate of 30 litres per bather per day, or water can be fully drained each day; the backwash cycle can be utilised to achieve this. The spa should be plumbed and valved to allow the booster pump to be used for backwashing. Note: Never operate the filter multiport valve while the filter pump is running, otherwise serious damage to the filter and valve may result. Page 14

19 Backwashing For Zeolite or sand filters: Switch off the filter pump. Turn multiport valve to backwash - this will reverse the water flow through the filter. Switch on the filter pump to wash any debris out of the filter to waste. Leave running for 3 to 5 minutes, or until sight glass is clear and then switch off. Turn the valve to rinse (sand filters only) - this returns the flow of water to the normal direction and settles the sand bed. Switch on the filter pump. Water continues to flow to waste. Leave running for 2 to 3 minutes and then switch off. Turn the multiport valve back to filter to return to normal use. A considerable quantity of water can be lost from your spa during the backwash cycle and it needs to be replaced. Check and adjust the chemical levels before using the spa. The principle is the same for Diatomaceous Earth filters but the backwash mode is selected by moving a lever valve at the base of the unit. For specific instructions refer to the manufacturer's guidance in the manual supplied with the pack. Page 15

20 Final Filling Clean the spa shell using spa polish to protect and seal the surface prior to filling. Sanitising When filling the spa always Superchlorinate the water by adding 20g of Chlorine per 1000 litres/220 gallons of water to raise the Chlorine content to approximately 10mg/l (wait until level is below 5mg/l before using the spa). Water Balance Immediately after filling/diluting and Superchlorination of the spa water, test and adjust the water balance as necessary. Mineral Protection To prevent staining of the spa surface and water discolouration caused by metals in the source water, use Swimmer Scale Inhibitor. This will help prevent scale accumulation, however, maintaining the water balance will prevent excess scaling. If applicable, the automatic chemical dosing unit can now be fitted. Refer to the system manual for installation, commissioning and operation details. Please see additional information at the end of this manual for recommended guides on water treatment. Page 16

21 Testing and Completing Testing A 24 hour flood test is recommended prior to finishing the spa surround. Whilst filling the spa or balance tank (if fitted), via a break tank, ensure the water is treated as recommended (see final filling below). Ensure all valves are open; prime and bleed pumps as required prior to running. Check all plumbing joints from the spa to the equipment and balance tanks. Leave the spa to stand for several hours. Check the water level remains stable. If the level drops and it is due to a leak, locate and repair. Repeat the process until level remains stable. Run up the equipment, checking the operation of each component via the touch pad. Priming the Pump The pump must have a coarse strainer and if the equipment pack is above the water level* it may need priming as follows: Remove the lid and fill with water to above the basket rim. Re-fit the lid and ensure the rubber O ring is seated correctly, hand tighten only. * The balance tank (if fitted) must be at the same level or below the base of the overflow channel, it cannot be above. Page 17

22 Testing and Completing Checking the Filtration Operation Switch on power to control box. The filter pump should start. Check the filter pump is running then check if there is water flow in to the spa. If there is no movement, refer to the pump priming instructions above. Note: the filter pumps will only operate if the water level in the balance tank is at the correct level. Checking the Heater Operation Set the temperature above the actual water temperature, if there is sufficient water flow the spa heater will come on. Slowly close the suction valve to check the flow switch shuts off the heater when flow is restricted. Checking the Jet Equipment Depress the jet button on the spa to activate the hydrotherapy jets. Check the jets for a flow of water. If there is no flow, refer to pump priming. Ensure jet positions can be altered by hand. Check any rotating jets spin freely. Unscrew the air controllers on the side of the spa to ensure air is induced into the jet system. Check air blower operation, depress button on the spa. Ensure air is coming up from all areas of the spa where holes have been drilled. (i.e. seat and floor) Leave the spa running for approximately 1 hour. Allow the spa to heat up to the operation temperature and leave on filter only. Check the plumbing joints again. Page 18
